Summary: Prevent stuck keys in OS X DHTML

Bugs Fixed: LPP-8210 - phantom keys marked as down in DHTML  
lz.Keys.downKeysArray if you use the Apple key in OSX

Technical Reviewer: hminsky
QA Reviewer: ptw

Details: LzKeyboardKernel - Track meta (apple) key in __downKeysHash.   
Add __keyCodes hash to store original key codes for use later - so  
they can be retrieved based on the string value.  Prevent sending 224  
- meta key events.  If detectstuckkeys quirk is on (currently only OS  
X) detect keys that may still be down when the meta key goes up.  If a  
stuck key was found, generate an appropriate keyup event.

LzSprite - Add detectstuckkeys quirk, enable for OS X.

Tests: lz.Keys.downKeysArray no longer has extra entries for meta  
keys, e.g. 'a' after pressing/releasing apple-a.
